The afternoon session of today's Dewan Rakyat sitting turned rowdy after Jelutong MP RSN Rayer called for PAS president Abdul Hadi Awang to be investigated for endangering democracy.
Rayer, of DAP, referred to a news report quoting Hadi, the Marang MP, speaking about a change of government.
"Marang said that the other side was planning to topple the government," he said.
"I ask the home minister to investigate this as it is against the Penal Code under Section 124B.
"This is the government that was ordained by His Majesty," he added, referring to the Yang di-Pertuan Agong.
Misbahul Munir Masduki (PN-Parit Buntar) however objected, saying Hadi had made a political statement and was not planning to topple the government.
He also called for Rayer to retract his statement.
Rayer however maintained that Hadi had acted in disobedience to the Agong.
A war of words then erupted, in which Rayer was challenged to lodge a police report over Hadi's remarks.
The chaos was reined in by deputy speaker Alice Lau, who turned off the MPs' microphones.
"I ask for this matter to be given attention," Rayer maintained.
"The people cannot be left to languish if something happens like what was planned by the opposition."
Hadi was reported as saying that Perikatan Nasional had the right to make plans to topple the government led by Prime Minister Anwar Ibrahim as this was a democratic right.
